Our son and daughter use Dolfin AquaTech Goggle for daily club swimming and long distance swim (1.5 mile). Although they use speedo vanquisher for swim races, they prefer this google for daily practice because it's more comfortable (around the eyes) and cheaper than the speedo vanquisher googles. We had introduced this to our friends, both kids and adults like them.

Goggles did not fit and were not water tight. They hurt my nose. I gave them away since I had already discarded the shipping invoice before I used them.There were no sizes listed in the product description. I compared them to another brand that I own and that was listed as"large". Obviously I need a pair in a large size. Did not get that here with these goggles. Beware.
